VANETs is embryonic equipment with encouraging future including great challenges. As of late vehicular correspondences frameworks entranced much consideration, fuelled to a great extent by the rising enthusiasm for Intelligent Transportation System. (ITS) It focuses at the basic issues like Safety of public and congestion of traffic by assimilating data and communication technologies into infrastructure of transportation and vehicles. It also includes the challenges along with the characteristics faced at the VANETs. Standard used in VANETs is also conversed in the paper. This paper discusses about the various layers in OSI model and the challenges occurred at layers and also present the possible outcomes to overcome those challenges.
